Question

С решением пожалуйста ​

Answer 1

13 7/12 + 42 1/6 = 13 7/12 + 42 2/12 = 55 9/12 = 55 3/4

$872 frac{5}{8} + 15 frac{25}{36} = 872 frac{45}{72} + 15 frac{50}{72} = 887 frac{95}{72} = 888 frac{23}{72}$

$473 frac{5}{12} - 362 frac{4}{21} = 473 frac{35}{84} - 362 frac{16}{84} = 111 frac{19}{84}$

$55 - 23 frac{51}{64} = 54 frac{64}{64} - 23 frac{51}{64} = 31 frac{13}{64}$

$11 times 4 frac{17}{31} = frac{11 times 141}{31} = frac{1551}{31} = 50 frac{1}{31}$

$52 frac{2}{3} div 13 = frac{158}{3 times 13} = frac{158}{39} = 4 frac{2}{39}$

Пошаговое объяснение:

$13frac{7}{12} +42frac{1}{6} =frac{163}{12} +frac{253}{6} =frac{163}{12} +frac{506}{12} =frac{669}{12} =frac{223}{4} =55frac{3}{4} =55.75$

$872frac{5}{8} +15frac{25}{36} =frac{6981}{8} +frac{565}{36} =frac{62829}{72} +frac{1130}{72} =frac{63959}{72} =888frac{23}{72}$

$473frac{5}{12} -362frac{4}{21} =frac{5681}{12} -frac{7606}{21} =frac{39767}{84} -frac{30424}{84} =frac{9343}{84} =111frac{19}{84}$

$55-23frac{51}{64} =frac{3520}{64} -frac{1523}{64} =frac{1997}{64} =31frac{13}{64}$

$11*4frac{17}{31} =frac{11}{1} *frac{141}{31} =frac{1551}{31} =50frac{1}{31}$

$52frac{2}{3} :13=frac{158}{3} :frac{13}{1} =frac{158}{3} *frac{1}{13} =frac{158}{39} =4frac{2}{39}$
